Which of these best represents an ecosystem?
{silence}Option A.{silence}
A herd of deer grazing in a field
{silence}Option Be.{silence}
Mushrooms decomposing organic matter
{silence}Option C.{silence}
A pitcher plant growing in nutrient-poor soil
{silence}Option D.{silence}
Frogs and fish swimming in a pond in the forest
The best option that represents an ecosystem is Option D. Frogs and fish swimming in a pond in the forest.
An ecosystem refers to a community of living organisms (plants, animals, and microorganisms) in conjunction with the non-living components of their environment (such as air, water, and land). Option D represents various living organisms (frogs and fish) interacting with their environment (pond in the forest), showcasing the interdependence and relationship between different species and their habitat.
